Patent number: 8790810Abstract: A battery cell module includes a battery cell, a sliding repeating element, and a guide rail. The repeating element is disposed adjacent the battery cell. A gap is defined between the battery cell and the repeating element. The repeating element has a main body with at least one spacer coupled thereto. The guide rail cooperates with the at least one spacer and permits the repeating element to move with an expansion of the battery cell. The cooperation of the guide rail with the at least one spacer thereby militates against an overcompression of the battery cell.Type: GrantFiled: December 14, 2011Date of Patent: July 29, 2014Assignee: GM Global Technology Operations LLCInventors: Barton W. McLaughlin, Michael A. Celotto

Patent number: 8790818Abstract: A multi-functional, laminated composite comprises a plurality of cloth layers (3) penetrated by an infused matrix, wherein at least one cell (1) for energy storage is supported by and integrally built up from at least one of the cloth layers (3), the cell (1) being embedded in the matrix. The cell may comprise first and second electrodes (6,7) separated by a porous, separator layer (2) that has a liquid electrolyte-permeable, matrix-free intra-electrode region to which the electrolyte (2?) may be added before or after resin infusion to activate the cell. The structural composite may have integrated energy storage comprising a lithium-ion rechargeable cell, optionally of printed construction.Type: GrantFiled: December 11, 2009Date of Patent: July 29, 2014Assignee: Qinetiq LimitedInventors: Fazlil Ahmode Coowar, Mark Andrew French, Gary Owen Mepsted, Christopher Douglas James Spooner
